DeepSeek blog post validator

Submit a blog post drafted with DeepSeek and this tool checks for the structural habits that recur in that specific output: heading styles that shift partway through, a leftover line describing the draft's revisions sitting where content should be, a register that drifts from formal to casual, and claims left without a stated source.

The output is a set of flags, each with a stated reason, rather than a compressed score, evaluable against the actual draft rather than requiring trust in a single figure.

It's a server tool by necessity: judging structure and unsupported claims requires a language model too large for a browser. Five free runs are available in any rolling 24-hour window, with no account required.

One round trip returns a full set of structural and claim flags.

Step 1

Submit the complete draft, headings included, for review with full context.

Step 2

Run the check. The draft is sent once to our AI server and evaluated against structure and claims.

Step 3

Work through each flag against the draft, applying what fits and setting aside what doesn't.

DeepSeek's writing is frequently sound at the sentence level and uneven at the structural level: a heading style that changes between sections, a stray line describing what was revised sitting where content should be, a tone that shifts without warning. None of this constitutes a factual error, which makes it easy to overlook on a fast read, yet it is precisely the kind of inconsistency a reader notices even without being able to name it. The writer who produced the draft is typically the worst-positioned reader to catch it, having seen the same formatting throughout and stopped registering where it changes.

A recognizable set of habits recurs often enough in DeepSeek's default blog output to warrant a dedicated check.

Inconsistent heading formatting

A mix of heading styles or numbering conventions within a single post, where one convention should carry through.

Leftover process notes

A stray line describing revisions or considerations, appearing where substantive content is expected.

Register that shifts mid-post

A formal introduction followed by casually phrased sections, reading as unintentional rather than deliberate.

Claims stated flatly without a source

A specific figure or fact presented directly, with nothing behind it a reader could verify.

Readers scan before committing to a full read. Inconsistent heading styles interrupt that scan and make a piece appear unfinished even where the underlying sentences are strong, and a leftover process note occupying a content slot reads as an editing lapse.

Unsupported claims carry a cost regardless of what produced them: a specific figure with nothing behind it is among the fastest ways to make a reader distrust the rest of a piece, including sections that were accurate and well supported.

No, and a tool claiming otherwise merits skepticism. This tool checks structure, clarity and unsupported claims specifically. It has no visibility into search ranking, which depends on factors this validator does not evaluate, and it cannot substitute for a human editor's judgment on tone or fit.

What it reliably delivers is early detection of the specific, fixable habits described above. That is a genuine, bounded improvement, not a claim about outcomes it does not control.

Predominantly writers who drafted a post with DeepSeek and want it checked before publication.

Bloggers using DeepSeek as a first pass

Confirming formatting drift and leftover notes were cleaned up before the piece ships.

Content and marketing teams

A quick check ahead of human editorial review, resolving obvious issues before review time is spent.

Freelance writers

Checking a client-bound draft before delivery, catching formatting tells internally first.

Evaluating structure and unsupported claims requires a language model too large to run in a browser, so each check is a single round trip to our AI server rather than local computation.

That trip is metered rather than unlimited: five free runs in any rolling 24-hour window, tracked without an account, reopening as the window rolls forward. Each run also caps the input at about 12,000 characters, close to 2,000 words; DeepSeek's exhaustive, cover-every-angle style can run a post past that quickly.
